- Data presented as mean ± standard deviation number of interventions per day, providing a summary of the mean number of interventions for intracranial pressure control on days 1 to 5. Patients were divided into three groups based on their mean serum sodium value on each day of the study period. For each day, statistical comparisons were performed for the number of interventions required in each group.
